風機。 In an electric blower that has a disk-shaped rotor made of permanent magnets and is driven by a DC brushless motor with an axial magnetic gap structure, the yoke that faces the magnetic poles of the rotor is fixed to the stator. An electric blower is characterized by a structure in which some or all of the impellers, such as the propeller and the rotor, function as a magnetic material and a yoke, and the yoke rotates together with the rotor.
